Summary0007920: Picture Preview Saving
DescriptionWhat about a feature to save the picture previews in the sla (or any connected) file - if you have files with many pics in it, it takes several minutes to open the document because previews for all the pictures must be created once again...

There is no reasonable way to achieve this. We'd have to throw away some extremely useful properties of Scribus. The better solution is to make the code faster.

Generate the preview pics in a (hidden) tmp folder for each project.
Additionally you could generate a md5sum for the original pics and store this in the tmp folder too. then you could check if the preview has to be regenerated or not by comparing the md5sums.

I generated md5sums for 387 tif files (about 50 MB) and it took only 2-3 sec.

there may be also an option to let scribus use the preview embedded in the picture... and if there is none, let it generate by an external library...

I think Issue 7169 is a duplicate.

I run some tests on my docs. Using images with lower resolution improves the speed a lot (but it is still to slow).
I managed to reduce the loading time to 3 min. After removing all images from this doc, it even took just seconds!

I think ale's solution is very cool (and maybe very fast) and it sounds not to be difficult to implement.

Using thumbnails sounds cool to me, too. The tmp folder (as suggested by aliB) would bring the advantage that even if the original file is deleted or moved, a low resulution thumbnails would be still available in the document.
