My thumbnail pictures created with this:
If(Length([Attachment File])=0,"","<img width=\"30\" src=\""&URLRoot()&"up/"&Dbid()&"/a/r"&[Attachment ID#]&"/e7/v0\"/>")
refresh unbearably slowly. When I create a new record or create the first [Attachment File] in the record, there is no problem. Contrary to that if i edit a record already having an Attached file and i change the file to another, it takes more than minutes for the thumbnail image to refresh.
Especially on a mobile device i need the thumbnails for the user to review the pictures taken in a report, so if an attachment file is changed, the report shall follow. But it - practically - doesn't.
In my tests so far there are not more than 6 or 8 recoerd with thumbnails in a report, so i am not querying hundreds of them...
Can I do anything to make the thumbnail refresh faster after edits? Am I creating the thumbnail picture the good way? Interested in any workaround if all else fails!
Thank You!
