1 Photo upload create in the /wp-content/uploads/* folder a lot of files

Hey br50com,
WordPress creates many different image sizes when you upload a image and chooses the appropriate file to show depending on screen size the device viewing the site, and the element showing the image. This is normal and intended. Although you can change these sizes using a plugin such as Simple Image Sizes or writing some code, but both of these options are meant for advanced users, most users will find the built in sizes are the best option.
I hope this helps explain it.

Best regards,
Mike

Hi,
Sorry, I’m not sure I follow.
I understand that you have 10k photos to upload, so all the extra files is no good.
Then I think you are saying you only need two sizes for each image?
If this is true, you can remove some of the sizes in the functions.php look for:

/*
 * Register additional image thumbnail sizes
 * Those thumbnails are generated on image upload!
 *
 * If the size of an array was changed after an image was uploaded you either need to re-upload the image
 * or use the thumbnail regeneration plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/
 */

$avia_config['imgSize']['widget'] 			 	= array('width'=>36,  'height'=>36);						// small preview pics eg sidebar news
$avia_config['imgSize']['square'] 		 	    = array('width'=>180, 'height'=>180);		                 // small image for blogs
$avia_config['imgSize']['featured'] 		 	= array('width'=>1500, 'height'=>430 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize']['featured_large'] 		= array('width'=>1500, 'height'=>630 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize']['extra_large'] 		 	= array('width'=>1500, 'height'=>1500 , 'crop' => false);	// images for fullscrren slider
$avia_config['imgSize']['portfolio'] 		 	= array('width'=>495, 'height'=>400 );						// images for portfolio entries (2,3 column)
$avia_config['imgSize']['portfolio_small'] 		= array('width'=>260, 'height'=>185 );						// images for portfolio 4 columns
$avia_config['imgSize']['gallery'] 		 		= array('width'=>845, 'height'=>684 );						// images for portfolio entries (2,3 column)
$avia_config['imgSize']['magazine'] 		 	= array('width'=>710, 'height'=>375 );						// images for magazines
$avia_config['imgSize']['masonry'] 		 		= array('width'=>705, 'height'=>705 , 'crop' => false);		// images for fullscreen masonry
$avia_config['imgSize']['entry_with_sidebar'] 	= array('width'=>845, 'height'=>321);		            	// big images for blog and page entries
$avia_config['imgSize']['entry_without_sidebar']= array('width'=>1210, 'height'=>423 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize'] = apply_filters('avf_modify_thumb_size', $avia_config['imgSize']);


$avia_config['selectableImgSize'] = array(
	'square' 				=> __('Square','avia_framework'),
	'featured'  			=> __('Featured Thin','avia_framework'),
	'featured_large'  		=> __('Featured Large','avia_framework'),
	'portfolio' 			=> __('Portfolio','avia_framework'),
	'gallery' 				=> __('Gallery','avia_framework'),
	'entry_with_sidebar' 	=> __('Entry with Sidebar','avia_framework'),
	'entry_without_sidebar'	=> __('Entry without Sidebar','avia_framework'),
	'extra_large' 			=> __('Fullscreen Sections/Sliders','avia_framework'),
	
);



avia_backend_add_thumbnail_size($avia_config);

and remove the ones you don’t want, be sure to save a copy of the original file should you make an error.
Or you can use the plugin above and set the size to zero for the images you don’t want, this might be the best option.
After you remove your sizes please use this plugin: Regenerate Thumbnails
As you remove each size check your site to ensure the size you removed is not used elsewhere.

Hi,
You can also try setting the WordPress image sizes to zero at WordPress > Settings > Media
Perhaps this article will also help explain: How to Prevent WordPress from Generating Image Sizes
