For Wapict (images are sometimes ~50mb), I simply have an external queue with workers using OSProcess to convert images. Not terribly efficient but works well enough.<br>
<br>
To generate thumbnails of, say, profile pictures on a website, I don't really know what I would use. Have you found any pure-smalltalk image manipulation library?<div><div class="h5"><br>

Hi--<br>
<br>
what's the recommended / popular way of doing basic image handling in<br>
Seaside? My requirements are to take uploaded images and make<br>
thumbnails in a few different sizes. I see some references so SMagick<br>
and to Smalltalk-local image handling around, but I'm wondering what<br>
general practice is among posters on this list.<br>
<br>
thanks<br>
