How to recover the deleted or lost photos, pictures and images?

You have lost the only copy of precious photos, and you need to recover them. Recovering digital photos from hard drives, memory cards, digital cameras and other players is one of the most common data recovery tasks. Digital storage media are quite fragile compared to photographic prints, and digital camera users often make just a single copy of their precious pictures before deleting the original. This results in tragedy when the copy cannot be read.
If some of your irreplaceable photos seem to be lost, don't be upset! Unless the medium on which they are stored has been physically damaged, there is a great chance that you can get them back. However, if the images were stored on a rewriteable medium such as a hard disk or memory card, never try to write new files to them before all the options for recovering the data have been exhausted.
The easy recovery software - Data Recovery Wizard will recover the lost, deleted and formatted digital photos from hard drive, removable media or digital cards. As long as these storage devices can be recognized in your computer, our product can get your lost data back.
Another common situation is that an error popped-up window may ask you "Media is not formatted, would you like to format now?" when double clicking on the device. Please don't click "Yes" to format it. The Data Recovery Wizard will save the day! Our data recovery software can easily recover the lost digital photos, Audio & Video files from removable media as well as hard drives.
Data Recovery Wizard is helpful in the following cases of data loss:
  • Provide Image Recovery after corruption caused by that the card is pulled out while the camera is on.
  • Provide Photo Recovery after corruption caused by that the camera is turned off during a write process.
  • Provide Digital Media Recovery after the digital storage media formatted.
  • This Picture Recovery utility recovers data lost caused by using media between different cameras/computers.
  • Provide Picture Recovery after accidental deletion of the photo.
Use the Data Recovery Wizard to recover photo images, movies and sound files such as BMP, JPG, JPEG, TIFF, PNG, GIFF, MP3, WAV, MPEG, MPG, AVI and MOV from floppy, Memory Sticks, Flash Cards, Sony Memory Stick, IBM Micro Drive, SD Cards, MMC Cards, XD Cards, Secure Digital Card, Hard Disks, Zip Disks, Mini Disks.
Accidental deletion from the hard disk
If you accidentally deleted the photo images from your hard disk, please:
1. Check the Recycle Bin.
2. If they are not in the Recycle Bin, please use the Data Recovery Wizard for data recovery.
3. Deleted files (including photo images) may also be recovered by using the Data Recovery Wizard.

Recover the photos from a memory card

If the images you want to recover are on a Flash memory card or in your camera, please:
1. Connect the memory card, camera or player so that it can be accessed like a removable hard drive.
2. Use the specialized digital image recovery tool - Data Recovery Wizard
To recover data from a drive containing lost photos, follow these steps:
1.  EaseUS Data Recovery Wizard, install it and launch it so please visit this site and Download software http://www.easeus.com/datarecoverywizard/recover-lost-photo-images.htm

Information Computers


The mechanism to simulate a regular mail into an e-mail, gave us a very fast and much cheaper medium to communicate (not a simulation anymore). Same way, using computers we can simulate other things over which we do not have any control, for example weather, behaviour of atomic bomb, behaviour of a deadly virus, Earthquake, a innovative design for a new auto, airplane, machine, etc.
Any computer has five parts Input, Output, CPU, Memory, disk (storage) . Input is things like mouse, keyboard, modem. Output is computer screen, printer. CPU or central processing is brain of the computer which controls and execute all calculations, manipulations and output. Memory (RAM)is a temporary storage to be used by CPU when doing calculations, etc. Think of it as a scratch pad for CPU. Disk is permanent storage, on which all the software and data is stored.
system.

A database is a software which lets user to organize their data in an orderly fashion. For example consider a company which sells cookies, they have a database of which has tables (or records) of customers, types of cookies and orders. So when customer x orders n number of x type of cookies his orders is placed in table orders. There are several type of databases. Some which are simply text files with records, others which are complex with tables of information. A table of information means "an array of one type of records", for example "an array of customer names, addresses, phone numbers". A Relational database is in which there are relations among the tables, for example consider three tables with customer info, inventory info and orders info. The relations between these three tables define the relational database. So when a customer X from customer table orders Item Y from Inventory info it is put in Orders table, there are links in these tables (through primary keys, secondary and foreign keys such Social Security number, product number, order number, etc) which lets us do that and thus making it a relational database. Popular type of relational databases are Access for PCs on windows 95, Oracle, Sybase, Informix, for huge business environment (running Unix operating systems).

Internet is a bunch of computers connected to each other. It started out when about 10 computers running Unix operating systems serving US military were connected to each other and named ARPANET. Initially, users could only send an e-mail to each other, deploying UUCP (unix to unix copy using modems) method. Then more computers from universities were added to ARPANET and research individuals started sharing their notes over e-mail. Later came Usenet which was more or less a discussion forum. Then after tremendous innovations in hardware (networking), in 1992 came Web, or the software called web browser which could display pictures and text. REST is history. Some terms


Programming languages are designed to aid humans to write code for computers. Since computers only understand the language of o's and 1's, and we humans a common english like languages, several computer languages were developed which translate code to computer language. Programming languages like C/C++,Visual Basic, Java using these a person writes a code and then compiles it and creates an executable file which is understood by machine. All .exe and .class files are executable files translated into language understood by computer.


Networking constitutes of connecting PCs and other machines with each other. If you have bunch of computers in same building connected to servers through several hubs it is a Local Area Network, like in an office building. If you have many buildings with many computers connected to each other it is a WAN or wide area network, like Universities. Going by same terminology Internet is probably Global Area Network. Servers are those computers which control user access to files, and are running all the time. All of the computers which are connected to Internet are servers since Internet demands access to information round the clock. When you use modem to connect to Internet on your Personal computer, you are connecting to a computer which is connected to Internet.

Operating systems are that piece of software which communicate with computer and converts all user commands back and forth. Operating systems have four parts which are Process manager, Memory manager, I/O manager and . Popular operating systems are Windows 95, Windows 98, Windows NT, Mac, SunOs, Digital, HP-UX, Solaris, Aix, etc
