@Chris take a look at this www.joomlaworks.net/forum/k2-en/47685-k2-image-upload-hide-k2_image_was_not_uploaded-notice#161508

@Mailson and @John are you talking about the frontend or the backend?

@ Krikor
Yes!! I've added the two lines of code and it worked!!
Thanks a lot!!

@Mailson and @John try this
administrator/components/com_k2/models/item.php line 276
if (!empty($image)){ //added check if $image is empty

and line 440
}// end check if $image is empty

Nice to hear this :)

the problem is at backend.

Tried above mentioned changes in administrator/components/com_k2/models/item.php line 276. But Image is not uploaded, only the error message disappeared.

the problem is with php7, I can upload image if I change to php5.6 from cpanel. I am getting too many error message from other extension if I use php5.6. so every time to upload image to k2 I have to change php version .

Can you upload images through the media tab?
2.8.0 will be released within the next days as well.

not working through media tab, I can wait for 2.8.0 . thanks

Ifyou have a DEV environment you can try it out.

The image does not appear and displays the message "
Image not uploaded. Please make sure that you have used a valid image file and that the file upload is configured accordingly on your server".

I use J 3.7, PHP 5.4.16 and K2 2.7.1

Information system
Web server Apache / 2.4.6 (Red Hat Enterprise Linux) OpenSSL / 1.0.1e-fips PHP / 5.4.16
PHP version 5.4.16
MySQL version 5.5.52-MariaDB
GD Picture Library Disabled
Multibyte string support Able
Upload limit 100M

Need HELP.

After update to J 3.7.2 and K2 2.7.1 we have the same problem

We update to k2 2.8.0 and not working in php 5.6 o php 7.0

We just install php-gd and it works in all versions

K2 2.7.1 + Php 5.6 OK
K2 2.7.1 + Php 7.0 OK
K2 2.8.0 + Php 5.6 OK
K2 2.8.0 + Php 7.0 OK

Try to install php5-gd or php7.0-gd, it works for us

Thanks Javier Romero,

Its working.. problem fixed , thanks again

@Javier, was GD not installed in the first place, or was it outdated?
