Watch your bandwidth consumption. If you set the fetched thumbnail
size much higher then your display needs then you really drain the
bandwidth to load the page, also if you increase the number of fetched
thumbnails too high as well.
I put the options in a comment by the function so I can remember what
they are in couple months when a change is needed:
function GetURLFullSize(entry)
{
var content = entry.content;
var start = content.indexOf("<img src=")+10;
var stop = content.indexOf(".jpg",start)+4;
var thumburl = content.substring(start,stop);
thumburl=thumburl.replace("_m","_s");
/*
Possible Sizes:
_s = 75x75 square
_t = 100 wide
_m = 240 wide
_d = 500 wide
_b = 1024 wide
_o = original file *must be coded differently
*/
return(thumburl);
}
