Title: adding or uplaoding slides Last modified: August 20, 2016 --- # adding or uplaoding slides * Resolved [dancingdog](https://wordpress.org/support/users/dancingdog/) * (@dancingdog) * [13 years, 6 months ago](https://wordpress.org/support/topic/adding-or-uplaoding-slides/) * Hi, I may be missing something very obvious, but how do I actually upload a slide? I go to **Add new Slide**, enter the caption and title. Under ‘Slide Image’ there is a link for ‘set featured image’ which brings the uploader screen; I choose an image, upload, then click ‘post thumbnail’ – and the uploader box closes bugt the ‘set featured image’ box stays up with a white screen. If I close it, there is no change to the ‘add new slide’ form. * If I repeat, and instead choose from media gallery, then nothing happens when I click an image thumbnail to select it. Is this how it is meant to work? * thanks… * [http://wordpress.org/extend/plugins/captain-slider/](http://wordpress.org/extend/plugins/captain-slider/) Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Author [Captain Theme](https://wordpress.org/support/users/captaintheme/) * (@captaintheme) * [13 years, 6 months ago](https://wordpress.org/support/topic/adding-or-uplaoding-slides/#post-3191353) * Hey!

Let me know if you’re still confused and I’ll make a screenshot for you. * Thread Starter [dancingdog](https://wordpress.org/support/users/dancingdog/) * (@dancingdog) * [13 years, 6 months ago](https://wordpress.org/support/topic/adding-or-uplaoding-slides/#post-3191361) * I don’t have a ‘set as featured image’ after uploading. I have ‘insert into post’ and ‘save all changes’ * If I click ‘insert into post’ then the entire uplaoder area goes white, (still in the overlay) with the ‘set featured image’ header. * Thanks fofr the reply * Plugin Author [Captain Theme](https://wordpress.org/support/users/captaintheme/) * (@captaintheme) * [13 years, 6 months ago](https://wordpress.org/support/topic/adding-or-uplaoding-slides/#post-3191366) * Does yours look like this? [http://d.pr/i/ABJQ](http://d.pr/i/ABJQ) * If not, your theme isn’t supporting featured images. * To fix, add the following to the bottom of your functions.php file: * ``` add_theme_support( 'post-thumbnails' ); ``` * If you don’t have this file or it’s empty, create it (functions.php) and add a: `
