Hello Massimo,

What you can do is to load up media manager, click on the image and click on the "Customize" button http://screen.stackideas.com/2015-06-10_0045.png. Upon clicking on the customize button, you should see a screen that look similar to this, http://screen.stackideas.com/2015-06-10_0046.png . Click on the new size and enter a new image dimension and click on the "Insert Image" button.

Hi Mark, I have not said I'm sorry, I have a problem with the image of the blog, unfortunately I get the key customization.
The key customization find it only when I want to add graphics to the content of the article, na not as the main image of the article Blog.
I hope I explained.

Hello Massimo,

Do you mean by the blog image? You can change the size of blog image from your backend > easyblog > themes > select your default themes > blog images, http://screen.stackideas.com/2015-06-10_2005.png . After saving, click on the clean image to remove old image from your cache. Unfortunately this is the only way to resize the blog image in easyblog with the current system.

Hope these help.
