I'm using ES File Explorer to connect to my Wi-Fi LAN, and to download images to my Hero. However, when I try to open them, i can see that the image app is starting and then suddenly stopping. I cannot open the images at all. However, if I connect my Hero to my PC and mount the SD card, I can open and view the images on both the computer and my Hero. I tried different image formats (jpg, bmp, gif)... All other file types are working fine (txt, doc, pdf...). Anyone noticed any similar issue?
