For Creative Galleries
If your images are blurry the cause of this is likely that you have set the minimum size of your images too low. As a general rule of thumb, it should generally be set to around 500 when using the Creative Gallery grid style. When used incorrectly, this setting prevents Modula from rendering your images in the high-res they deserve.
For Custom Grids
If you are experiencing blurry images after updating Modula lite/Modula Pro to version 2.5.1, go to your Custom Grid galleries and make sure you have “custom” at image size setting (general speaking this is a Custom Grid gallery issue). We rethought the sizing system and added some enhancements to images that will benefit in the long term.
