Title: Error when uploading same image twice Last modified: January 8, 2020 --- # Error when uploading same image twice * Resolved [thema3x](https://wordpress.org/support/users/thema3x/) * (@thema3x) * [6 years, 5 months ago](https://wordpress.org/support/topic/error-when-uploading-same-image-twice/) * Hi, Thanks for the plugin. I use the form to allow users to submit own posts including image. However if the same image is uploaded twice, second time it throws the error below: * ( ! ) Warning: imagepng(F:\WAMP\www\wordpress/wp-content/uploads/2020/01/e461- H1WKC2IwfPMzpng-300×166.): failed to open stream: Permission denied in F:\WAMP\ www\wordpress\wp-includes\class-wp-image-editor.php on line 484 Call Stack # Time Memory Function Location 1 0.0002 416888 {main}( ) …\index.php:0 2 0.0006 417168 require( ‘F:\WAMP\www\wordpress\wp-blog-header.php’ ) …\index.php:17 3 0.2626 6395080 wp( ) …\wp-blog-header.php:16 4 0.2626 6395128 WP->main( ) …\functions. php:1255 5 0.2626 6395128 WP->parse_request( ) …\class-wp.php:729 6 0.2643 6425872 do_action_ref_array( ) …\class-wp.php:387 7 0.2643 6425872 WP_Hook->do_action()…\ plugin.php:544 8 0.2643 6425872 WP_Hook->apply_filters( ) …\class-wp-hook.php: 312 9 0.2643 6427000 usp_checkForPublicSubmission( ) …\class-wp-hook.php:288 10 0.2651 6436472 usp_createPublicSubmission( ) …\user-submitted-posts.php:276 11 0.3108 6696032 usp_attach_images( ) …\user-submitted-posts.php:1154 12 0.3244 7163536 wp_generate_attachment_metadata( ) …\user-submitted-posts.php:1038 13 0.3247 7163984 wp_create_image_subsizes( ) …\image.php:476 14 0.3288 7168264 _wp_make_subsizes( ) …\image.php:362 15 0.3462 8999664 WP_Image_Editor_GD->make_subsize()…\ image.php:435 16 0.3707 9222272 WP_Image_Editor_GD->_save( ) …\class-wp-image- editor-gd.php:275 17 0.3707 9222760 WP_Image_Editor_GD->make_image( ) …\class- wp-image-editor-gd.php:433 18 0.3708 9222760 WP_Image_Editor_GD->make_image( )…\ class-wp-image-editor-gd.php:504 19 0.3708 9222736 imagepng ( ) …\class-wp-image- editor.php:484 * ( !

Can you please list the steps required so I can replicate the issue and investigate asap. For example, the steps should look like this: * 1) Install WP, leave all settings at default 2) Install USP, leave all settings at default 3) Change the Max image setting to some number 4) Try to submit two images 5) Etc. * So that anyone, anywhere could follow the steps and recreate your same issue.

After I changed these settings I submit the post from the form including the required image. So far so good. I’m able to approve the post and it looks fine. 2. I added a second post and attached the same image. Now the error happens but the image is uploaded successfully and the post after approval seems fine. Just after the submission, I hit [https://www.screencast.com/t/4EqBHZQgu](https://www.screencast.com/t/4EqBHZQgu) and the url seems fine [http://localhost/wordpress/add-new-post/](http://localhost/wordpress/add-new-post/). If I refresh it the submission page is loaded again. My observations so far: If I attached the same image but change the name it is all fine. So there is an issues with same names of the images. Also in the Media tab I have both images but the second has no extension and has changed name [https://www.screencast.com/t/LUsyuuNzvHH](https://www.screencast.com/t/LUsyuuNzvHH) * Let me know if I can help further - This reply was modified 6 years, 5 months ago by [thema3x](https://wordpress.org/support/users/thema3x/). * Plugin Author [Jeff Starr](https://wordpress.org/support/users/specialk/) * (@specialk) * [6 years, 5 months ago](https://wordpress.org/support/topic/error-when-uploading-same-image-twice/#post-12306132) * That is great information thanks.

I’m running the current version of USP on latest default WP install. Trying to upload the exact same image in consecutive posts always results in a random string appended to any duplicate file names (and no errors). * So I’m not sure what’s happening in your particular case, but you may want to troubleshoot your plugins and theme, they might be conflicting with image uploads somehow.
