Image browser problem after Ignition update

Dear Inductive Team,

Recently we updated Ignition from 7.2.5 version to 7.5.1. Before update, we have taken the Gateway Backup on 7.2.5 and uploaded this into new Ignition 7.5.1.

After above update, We are not able to see few images in Project View and In designer (both). We searched for this problem in forum. And saw few messages from Moderators and other members. They mentioned of unsupported images exist in the previous version. And also mentioned of removing those.
We searched for few image types like GIF, ICO etc. and deleted the same. We had only JPG and PNG in our projects.

But still, if we upload new PNG files, the images are not getting displayed. Not only these, few exiting images also not getting displayed and there is now pattern for this issue. In addition to this, the Image Browser is dead slow to open.

What is the issue with Image Browser in Ignition 7.5.1 ? If unsupported images are exist in previous version, then How those files are allowed in 7.2.5 (we mean earlier) version and not allowed in 7.5.1 ? The old projects, images worked well in previous version. What is the problem with new version ? What are the image formats not supported in New version ? How to find the issue with Image Browser ? Why we are not able to see few old images ? What is the problem with uploaded PNG images ?

Thank you

There are some unsupported image extensions that can make their way into your project. This will slow down the Image Browser. Also, some supported images can slow it down as well. This could be because of image corruption, or some other reason. The solution that has worked for others is to delete images one at a time from the image database until the issue is resolved. The supported image files are:

.gif
.jpeg
.jpg
.png

And of course your can bring in SVG files.

Other users have successfully resolved this issue by deleting images from within the Ignition Gateway Configuration. The following forum thread has some suggestions and also explains how to delete images from within the gateway console.

Some other things that you can look at as well

Do you have any antivirus installed?

Are you using roaming profiles? This can also slow things down sometimes

You can turn on logging for ignition.client.imageloader inside the designer under Help>Diagnostics. This may give you an indication as to what the problem is.

Thank you Greg for your valuable suggestions.

We will do as you mentioned (deleting one image at a time and check it out). We are using Online Server (Operating System: Web Server 2008) in which Antivirus is not preferred. It has HIDS (Host-based Intrusion Detection System) in place.

Yes, We are using roaming profiles. From your points, We need to take care all these issues. We enabled ignition.client.imageloader in Designer. Let us come back to you with our observation.

Ok.

The application either shows a black screen or sometimes it wont open the Popup window( in this case i had to reopen the ignition application to resume proper operation)
i am using Ignition platform 8.1.5
