Where do I change the image sizes in Newspaper

Hello,
Unfortunately thumbnail sizes cannot be changed so easy as they are fixed and set by us to align properly with the rest of the content. If you want to have bigger images on blocks, then simply chose a block that displays a bigger thumbnail. You can see see different content blocks here: http://demo.tagdiv.com/newspaper/block-1/ If you are referring to the big image at the top of your page, that is a custom added image, not a featured image. You can edit that element by editing the page in visual composer.
Thank you!

Hi,
Instead of paying money to a developer to modify the theme files and having to re-add the modifications on updates (custom modifications are not update proof even if a child theme is used) why not select another block for your content that uses a different thumbnail like for example: http://demo.tagdiv.com/newspaper/block-6/
Please try to select different blocks from the menu to see how they display images. There are 21 blocks to chose from and each have different image sizes.
Thank you!

Hi,

You can change the thme files if you want to do it and simply copy the image dimension from module 4 into module 2 (used on block 4) like so: http://screencast.com/t/f6zIvYDb
this will also affect the module 2 on category pages and also block 2 that uses the same module.
Then you will need css for the titles and excerpts to align to the new dimension:
you can add a margin-top value like so:

.td_module_2 .entry-title{
margin-top:80px!important;
}

Then you will have to adjust it for responsiveness as any modification will cause other effects when other devices are used.
for this you simply have to copy the code in the advanced css fields and change the value for each device

Hope this helps.
Thank you!
