    If you manually run the .jar file with administrator privileges, does it show up in Task Manager, and, if so, does it give an error? If the program shows up and no error boxes open, is it not changing the image in the folder it is placed, or is your OS not updating the desktop?

    Another possibility thatI've noticed is that the .jar file might have a network issue that doesn'tresult in an error. A slow connection or a network side firewall might be theissue. Does the Command Prompt window stay open when it first runs, or does itclose quickly? Also, if you get any errors, do do they say if the error was in writing the image orif it was in getting the RSS?

    If the jar file won't create the file, it is possible that the version of Java on your computer isn't up to date, but it seems more likely that the jar file doesn't have access to change the folder. You can try right clicking and selecting "Run as Administrator" or just moving it to a different folder such as your desktop and trying it there. Do any error boxes show up when it runs?Also, the registry won't save that setting. As long as the decimal number stays the same.

    I don't have any access to a PC with Windows 7, so I can't test it, but I just updated the file to instead keep two files instead of deleting one. This should work, just select both files after running the program once.

    Do you know if your slideshow changes when there are multiple images in the folder?

    If your source has a set link where you can find the image's URL (my program uses an RSS feed from NASA) then you can modify the code in Main.java, on my GitHub, to use this instead. Namely that would mean changing lines 29, 34, 41, and 42. I don't think I can go too in depth in just this comment, but I can give an image to help identify what's what. The top is a part of the RSS file from NASA and the bottom is my program, starting at line 26. Red = URLGreen = The "section" of importanceBlue = Tag nameLight Blue = A part of the tag name/more identifiersMagenta = The link to be gotten off the internet by the program.

    I can't guarantee anything with XP, but there seems to be one solution: the Windows PowerToys FunPack. This is the only solution I could find, but it seems like it has low ratings because it requires Windows Media Player to be installed as version 9.

    0. The startup folder is built into Windows, and is plainly named "startup." You can open it by typing "shell:startup" into the run dialog ([Windows Key] + R.)1. You can add the .BAT file by downloading from this page then moving the file (right-click > Cut) into the startup folder mentioned above (right-click > Paste.)2. Once inside the startup folder, you can right-click the file and then click on the "Edit" option to edit the file.3. You can place the "Refresh Image.jar" file anywhere you want, but the folder should be new so there are no other files in it.4. The "Main.java" program is the same as the "Refresh Image.jar" file I provided in the Instructible.
