the *first time* the timed portlet is running the fade effect looks broken:

instead of
fade out
change image
fade in

it does:

fade out and fade in again
switch to next image

testing on localhost fade in and switch to next image happen very fast, but one can still see that there is something wrong

if you can't reproduce it on your machine, i'll mail you a link to one of our development servers.
Steps to reproduce:
create a gallery
create a gallery portlet (timed)
navigate to the page that shows the portlet

Any chance you're using Plone 4? There was a fix for the portlet with that in the newer versions of ptg. Otherwise, I'll try to take a look at it later tonight. Thanks for the report.

i found out, that the porltet is using the size specified in the gallery-settings view.
if one chooses large there, also the portlet is using image_large.

such a unnecessary large scale together with slower connections might lead to the problem described above.

can we simply use a smaller scale for the portlet?

transitions look good now, thanks for fixing this so fast ;-)

i want to re-raise another question posted above:

do you think it's necessary to load the image_large scale in a portlet? image_mini or image_preview should be enough for this.
in case one sets the size to large in gallery_settings a portlet displaying this gallery uses image_large.

shouldn't portlet use image_preview in any case?

Yes, the portlet should use image large. What should happen is that the it detects the best scale to use for the size of the portlet.

I looked into getting this done last night, but it wasn't completely easy as it's somewhat a limitation of the design. In order to render the galleries faster, I cache the images retrieved. This is especially important when retrieving flickr or picasa galleries. When I cache them, I only cache the size that is selected at the time. What needs to be done is to cache all sizes and then it'll be possible in the portlet to grab whatever size is preferred there.

I'm going to close this issue and open a new one for this.

For now I suggest making another gallery the is essentially a mirror of the other gallery until this gets implemented.

No responses can be added.
