Is it possible to link images to different URLs?
You can do this using the Rewrite feature of Views.
These instructions assume that the view is set to show Fields (instead of Content or something else).  If you are not using fields, you can switch to fields under FORMAT in the Views UI.

Click the image field in your view and select the checkbox Exclude from display.
Add a new field to the view of type Custom text.
On the custom text configuration screen, check the Replacement patterns. This will include some twig tokens that you can use, including the image file. You can then use this token to add HTML to the Text field to get the link you want.  For example, &lt;a href=&quot;/mypage&quot;&gt;{{ image }}&lt;/a&gt;.

Note that when using Views twig replacement tokens in a custom text field, order matters!  If your custom text field is above another field, it won't be able to get the tokens from the field(s) below.  In that case, you will need to click the flippy triangle to the right of Fields in the Views UI and choose rearrange, and then move the field that uses tokens below the field(s) that supply the tokens.
Another option is to open up the settings for your image field in Views and, under Rewrite results, click Output this field as a custom link and set the link options there.
