Re: Problem with thumbnails since upgrade to 17.2/18.2
Just as another data point. Was creating a new image in a page and noticed the following. The code used is:
Copy to clipboard
{DIV(float="left")}||{img fileId="102" thumb="y" rel="box[g]" imalign="center" width="300px"}::__Calculating the GD from two 12 ((STR)) Marker testers__::||{DIV}
If I set the width to 300 or less, the thumbnail appears. If I used 400 or more, it does not. The original image is 976x145 pixels. If I set the width to "100%", the image appears. If I do not use a width, I get a tiny 100 pixel wide thumbnail and the image appears. This determination was made when viewed in a preview of the edit of page http://h600.org/wiki/Genetic+Distance
