Is there a way to get back emails that you threw away and then emptied the trash on yahoo mail?

Well, it was a picture I sent to my email from my phone and I kept trying to open the picture and save it to my computer,b ut it wasnt working and I deleted it and deleted my trash folder. =/ It was a picture I really want back, but it’s not on my phone either.

You can’t, but the Yahoo engineers possibly could - however, they would not do that at your request, nor would they do it routinely to snoop on you. They would try in the event that they were instructed to by an authorized law enforcement or similar security agency. It would then depend on whether the data files had been overwritten on their servers (including those providing “redundancy” to improve reliability).

Well, that bums me out. Is there a way to restore my cache or something like that to get it back? :(

If you have actually opened and seen the picture on a computer that you have access to, but have since deleted the image from that computer, it MAY be possible to restore the file on that computer (or better still another computer) - even if the folder it was in has been deleted, and the recycle bin emptied. But it becomes less likely to be successful the more the computer has been used as newer files become likely to have been written over on the HDD sectors in which the file was originally stored. Furthermore, if you never opened the image successfully on a computer that you have access to (even though you attempted to e.g. via an email attachment), it is likely that the file itself was corrupt and that is why you could not open it in the first place. We are in the area of “Data Forensics” here, and personally I would try myself if the image file was VERY important - e.g. as evidence in a mürder or similar investigation. This is what I would do if it was really so important: Turn off the computer and remove the hard drive. Connect the hard drive to another reliable and trusted computer as a slave drive. Make a “working copy” of the whole of the removed drive to preserve any original evidence of the original file that I was looking for. Use a reliable HDD sector scanner to locate sectors that contained data within the newly created working copy, but were not “pointed to” by the Master File Table” (MFT) on the working copy. Create new “dummy” master file table records for each promising block of previously active data that I located. Use the newly created dummy MFT records to recover new working copies of each recovered data block. Open those working copies (where possible) and inspect them to find the wanted file - if indeed it still exists without having been already overwritten on the original hard drive that I had removed. If I was doing this as a very big favour for a friend who was desperate to recover the file, I would either do it myself or give further instruction to the friend on how best to achieve these tasks successfully. If you think you have a chance of doing this yourself, the best I can suggest - if you consider yourself to be reasonably IT competent ( but a “data forensics” novice) would be to use the excellent freeware program REST2514 which will run from a floppy disk or similar removable media. http://funadvice.com/r/153l00ek4vm . However I must emphasize that the more you actually use the computer that you deleted the wanted file from, the more it is likely any deleted file (that are theoretically still recoverable) will be further damaged or completely lost when the drive sectors that were originally occupied by the file are reused by the operating system that has access to the drive.
