There is no issue about detecting an image is loaded, or if a web browser can access a local URL. We're trying to display an image, based on the part number of the item thats being produced on station. So if part number changes, image should also change. Issue is, PLC is getting that part number from an outside source. So, when a new part with new number comes, image should change. But since there isn't any image named like that in WebIQ project folder, it wouldn't show anything. To prevent this, a new image should be uploaded to WebIQ project workspace, before that new part is being produced. But, we want a program that runs without requiring an PLC programmer to connect to PLC and upload images to WebIQ project. If there is a simple way, like my examples, we can teach it to line engineers or operators, so when a new type is introduced, they can just upload images and station should continue. I sincerely hope I made it clear and hope you can understand it better now. Thank you.

Hello All, We're trying to display an image, based on the part number thats being used. So if part number changes, image should also change. Right now, we are passing a name variable from PLC. And with a localscript, when that variable changes we change the image path. For example, pics/custom/XXX.png , if variable from PLC is "XXY", it becomes .../XXY.png. Issue is, PLC is reading that part number from an outside source, and it can be anything. So, when a new part number comes, PLC reads and sends it, but since there isn't any image named like that in WebIQ project folder, it doesn't show anything. Is there a way to access that "pics/custom" folder from a PC, like mapping a network drive, or another way? If so, we can ask line engineers and operators to just copy their images, whenever they require, or periodically etc. Another idea we have is to access directly a folder from server, and we can just show those, but I'm not sure if we can enter a location url to image path, outside of workspace of project. We also have a PC for another process, but we can implement something like copying images from server and writing to WebIQ project folder. But that is just another way of impelementing my first suggestion so, if it is possible, this can work too. Thanks for all the help.

I understand your concerns. I'll definetly look in callback functions and possible problems, in detail. I'll write the result or issues afterwards. Thank you for your support.

Ok maybe I can explain differently because I think you are mentioning something entirely different. As you can see from attached image, there is an image area. We'd like to change this image, with every new part that is being produced in station. Our issue is, station produces more then 300 different parts. And, new ones can be introduced any time. So our solution is, we can provide "path" to image changer via a variable (ex: type number) from PLC. That way, we don't have to add 300+ items to image changer. I hope that makes it clear. So @Sgilk's example already provides a solution. My other question is, does local scripts runs when a variable changes? Or does it do when page changes? Since screen will be the same, we'd like to contionusly run the script, so when value from PLC changes, image will also change. I've checked every example in your download area, unfortunately I couldn't find anything releated to this. I'm happy to check if there are some more examples in different places, or same examples if you think I missed something.

Hello All, First of all, thank you @Sgilk for the example, that looks great. I'll try that asap. @webiq-sk Basically, we have different images for every part. And there are more then 300 parts. And there may be new parts coming once in a while. So, adding all of these to image changer widget is not feasible. What we thought is since we get part ID's in PLC, we can send this to HMI with a variable, and our widget can display that image with that name. Customer will put images in releated folder, so if image is in the file, we can call it with part ID, since the image name will be the same. So this might work. Only thing I don't know is, does the script updates when the variable from PLC changes? Because variables are the only things that will change, operator won't choose anything, and image should change according to that variable. Do you know if scripts change like this, or is there a function or something else we can use? Thank you.
