I have an image on my website, after a period of time (say 2 weeks) I change some details in the image.
For example: the image is sitting in Media > Folder > image.png
I click on image.png, click on Remove file(s), the upload the image (it has the exact same name, just perhaps a colour or some other details has changed), then click the Save button. The change is successful and I can see the image has updated to the new image in the Image tab which shows the image information. If I refresh the image on the website, I can also see there it has correctly updated.
When I click on Media > Folder, I can see all the thumbnails of the images in that folder. The thumbnail in this area does not change.
When I right click on the thumbnail and open in a new tab I can see the URL is as follows:
Umbraco uses Imageprocessor to create the thumbnails and save them in a cache. Since the name of the image stays the same and the parameters passed to image processor width=500&mode=max&animationprocessmode=first stay the same, Imageprocessor just serves up the item it has in its cache \App_Data\cache.
When you change one of the parameters, imageprocessor creates a new image and serves that one up.
Solution: clear the cache folder or upload an image with name image_v2.png
For more information on how you can use Imageprocessor yourself using Umbraco, look at this documentation
Replaced image - thumbnail not updating
I have an image on my website, after a period of time (say 2 weeks) I change some details in the image.
For example: the image is sitting in Media > Folder > image.png
I click on image.png, click on Remove file(s), the upload the image (it has the exact same name, just perhaps a colour or some other details has changed), then click the Save button. The change is successful and I can see the image has updated to the new image in the Image tab which shows the image information. If I refresh the image on the website, I can also see there it has correctly updated.
When I click on Media > Folder, I can see all the thumbnails of the images in that folder. The thumbnail in this area does not change.
When I right click on the thumbnail and open in a new tab I can see the URL is as follows:
https://mysite/media/1236/image.png?width=500&mode=max&animationprocessmode=first
This is showing the old version of the file. If I change the URL to...
https://mysite/media/1236/image.png?width=500&mode=max&animationprocessmode=last
it shows the correct image.
Is this a bug? Or is there something funky going on with my site?

Hey Margot
Welcome to the Umbraco community!
Umbraco uses Imageprocessor to create the thumbnails and save them in a cache. Since the name of the image stays the same and the parameters passed to image processor
width=500&mode=max&animationprocessmode=firststay the same, Imageprocessor just serves up the item it has in its cache\App_Data\cache.When you change one of the parameters, imageprocessor creates a new image and serves that one up.
Solution: clear the cache folder or upload an image with name image_v2.png
