Gif is played only when isThumbnail is true for a!imageField

I don't know why, but the following should work. Note the size: "FIT".

 

a!imageField(
  images: a!documentImage(
      document: cons!JXI_CAT
    ),
  size: "FIT"
)

That is a very good workaround Joubin, but now I am facing the same issue in a gridImageColumn

a!gridImageColumn(
size: "ICON",
isThumbnail: true,
data: a!forEach(
items: index(
ri!array,
"data",
{}
),
expression: a!documentImage(
document: cons!DOC_GIF_ICON
)
)
)

It looks like Appian does not currently maintain the gif format unless we use "FIT". By using "ICON", for example, and right clicking the image and choosing "Save Image As", the image type changes to "PNG"...

 

If you need the size to remain at "ICON", your quickest workaround may be to resize your gif to 20x20 (what Appian scales to when using "ICON") and then revert back to using size: "FIT". 

There are many gif resizers online - ezgif.com worked fine for me. 

 

I understand that this is still a workaround, but I hope this helps in some way.

Unfurtanetly FIT size is not available for gridImageColumn, apparently for now it is only possible to play the gif if the isThumbNail property is true, thanks for your help Joubin!

The following code solved my problem:

a!gridImageColumn(
label: "test",
size: "ICON",
data: a!forEach(
items: index(
ri!array,
"data",
{}
),
expression: a!webImage(
source: rule!APN_getDocUrl(
cons!DOC_GIF_ICON
)
)
)
)

Fantastic! Thanks for sharing your solution.
