Have you ever tried to import a .bmp file into Reshacker while you were working on a login screen and received an error similar to this:
Access violation at address ######## in module 'ResHacker.exe' Write of address ########.The ######## can be any number, since it's a hex memory address and will be different each time for the most part.
Well, that error is 99% of the time due to the .bmp file being created in Photoshop. While Photoshop is a top quality program, for some reason it's .bmp format won't import into Reshacker most of the time for some reason.
The Solution? After saving your .bmp file (in 72dpi resolution), open your .bmp file in MSPaint or another graphics editor that supports bitmap images. You don't really have to change anything after opening it up...just open it, and then go to File->Save As and save the bmp file overtop of the existing image. I don't recommend using just Save (File->Save) because often the program won't save the "new" image due to the fact that no changes were made and this was detected...no need to save it.
If you get that error, then try this to fix it. If you still get the error, try opening up the image in your alternative program (MSPaint for example) and maybe just color one pixel somewhere that won't be noticeable. Then save it and try to import the new image into Reshacker. In my experience, this works 100% of the time.
