I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,

I am trying to dynamically set the compression or quality of an image when displaying it. I have seen in the RMagick documentation how to set the quality only when writing the file to disk. How can I set the quality dynamically or set the compression? The method "image.quality=" does not exist and "image.compression_type=" is not in the documentation. I have tried

I''ve tried migrating acts_as_attachment to attachment_fu (just to see if I could replace RMagick with ImageScience+FreeImage), but the quality of the thumbnails is just horrendous, blurred beyond recognition (downscaling a 1280x1024 to a few considerably smaller thumbnails).
