Ok, first up well done to the them on the new exploit, talk about an amazing find!
One thing about it i found was that I couldnt look at any photos on the memory card, because as soon as the folder that the Tiff was contained in was opened, the hello world started!
So heres a quick hack/tip to have the exploit and viewable pictures. First off make a folder in the PHOTO folder on the memstick. Rename it to something appropriate, eg. Homebrew, or when it gets released, eLoader
Next copy the exploit into the folder. Now if you try the memory stick in the PSP, it will still load the Hello World as soon as you enter the Photo section on the menu. Why? Because its trying to do the thumbnail thing with the picture and apply it to the folder icon, which of course runs the exploit.
So find a random picture, rename it to be alphabetically before the exploit, and voila! You can now browse your photos with no interuptions, and if you wish to run the Exploit, just open the folder with the exploit in.
I know its a kind of a lame idea, but i thought it was helpful, probably more so when the eLoader appears. Keep up the awesome work!
