Wat do you mean exaclty by the sentence "to drag images into memory again?" (that sounds like a "no" :-) sorry) ? If you could be moore specific I could try to come up with something similar to a solution. > In general 2.4 is way faster - in specifics JPEG is always a problem > since you need to read the whole > file all the time. Well, that's a problem in most OS jpeg readers, Tthey are all actually quite inefficient. We could try to put together some workarounds by creating a new separate JPEG plugin but I don't have spare time at all to do it right now. One things that we should do over time is splitting the WorldImage plugin into separate plugins for each format (jpeg, gif, tiff) if we want to be a bit more efficients. Differents formats usually means different strategies to improve performances.
