When the thumbnail with size (over 500Kb) or extensions (.gif) not allowed is added on save window, the warning message is displayed but the resource is saved anyway.

How to reproduce

• click on new map
• click on save
• change the thumbnail with over 500Kb or a .gif
• click on save
• go back to the homepage
• search the map

An updated status for this issue is described below.

Description

If you save a map changing a thumbnail with a size over than the max allowed one (500kb) the map is saved anyway with a wrong thumbnail state.

How to reproduce

• Follow the steps in the animated gif (the map used for this is available here)

Expected Result

The same behavior of changing the thumbnail in home page should be respected: the map is saved but the thumbnail is empty and looks like the following:

Current Result

The thumbnail is in a wrong state, look at the animated gif. After saving the map the first time and reopening the map properties, the thumbnail is not changed in the UI. But, If I refresh the map and then I reopen the map properties the thumbnail is in a wrong state (it looks gray). If now I go back in the home page and I search for the map the thumbnail is in the same wrong state.

[ElenaGallo]

Now after a thumbnail of wrong size (over the 500 kb) is edded there are two different behaviors:

1. for the map, after saving the thumbnail with an oversize image, from the homepage, the thumbnail is empty
   

2. for dashboard, story and map (only from the map viewer) saving the thumbnail with a oversize image the thumbnail remains the old one
   

@tdipisa which of the two is the one to keep?

[tdipisa]

@ElenaGallo in my opinion it should be the second one. @offtherailz what do you think?
