Re the intermittent reporting of sizes: numerous "standards" (and wanna'-be-standards) call for <img ...> tags to include ... width="nn"... (where nn is a value in pixels) and height (similarly) arguments.

But, as with most things webbish, many programs and/or people ignore those standards, posting html like this:

<img src="/graphics/foo.jpg">

Your introductory line, "...parsing an image's size from a URL (not local path)" implies something very different than what jhourcle (above) discusses. That node may reflect your intent more precisely, but if I take your quoted remark litterally, I don't think it can be done because there's no info about the size(s) of any contained image(s) in a URL itself.

However, getting sizes from properly formatted <img...> tags at a URL is readily do-able if the code at the address in question actually includes the requisite info.

The only ready alternative (that I see but Nota Bene: jhourcle 's above) for sites using non-compliant image tags is to feed your program with full_paths_to_images (by name) and pipe the images to a graphics package or program such as ImageMagick or the gimp. (For that, you may want to search here re Tk + image or gtk + image, where you may find help -- pay special attention to anything Zentara wrote).

You may wish to start with Corion's notes here or -- if you need background on images especially note Merlyn's and thpfft's replies to the referenced node.

FOOTNOTE, UPDATE With considerable chagrin, I note that even as I toiled over this largely wasted observation, Brother jhourcle correctly ( inferred||intuited||leapt to the correct conclusion ); namely, that your question referred to the module Image::Size. IMO, it would have been nice to mention that explicitly in the OP.
