Unfortunately we don't have the ability to edit this dialog. BUT... with a little CSS magic you can add some additional info:
/* HIDE EXISTING TEXT */
div#quality_warning_images_list + p {
display: none;
}
/* ADD NEW TEXT */
div#quality_warning_images_list::after {
content: "But don't worry! Our team will contact you and help you get your artwork to the quality it needs to be.";
width: 100%;
float: left;
margin: 20px 0;
font-size: 1.3em;
font-weight: bold;
}
Adding this CSS will hide the line of text straight after the image which says "By clicking OK, you are agreeing to accept the final product regardless of image quality. Click Cancel if you want to go back and fix the images.", and the second part will display new text. You can edit the text in the 'content' part.
You could make the text say something like "You can upload a new design or continue and our design team will contact you later to get your artwork where it needs to be." Up to you
Another more extreme way to make this popup not seem like a barrier is to use this code:
div#quality_warning_div .popup_content h3, div#quality_warning_div .popup_content p, div#quality_warning_div .popup_content h4 {
display: none;
}
div#quality_warning_images_list::after {
content: "This design seems to be low quality and may not be suited to our design process. But don't worry! Our team will contact you and help you and get your artwork to the quality it needs to be.";
width: 100%;
float: left;
margin: 20px 0;
font-size: 1.3em;
font-weight: bold;
}
#alert_warning_warning_icon {
display: none;
}
