Beyond this, im out of ideas, so i hope that works.
Already tried both. Still nothing. I have no idea why the phone hates it's own pictures. I tried emailing them to myself too, they still don't show up in the gallery. The only way I can open them is to use Androzip and open them with the gallery manually one by one.
Edit: I just decided to throw the microSD card that came with the phone into my computer (I never even used it, went straight to my own memory card), and transferred the Sample folders to my phone and they now show up in the gallery. As well as the ones I saved from my email, which previously did not.
