redhat enterprise linux – What is the driver update image file?

I am running an installation of RHEL 5.11 on my server. Since my server's DVD-ROM does not work, I have decided to create a multi-boot USB disk using YUMI. Everything works during disk creation, I select the RHEL5 ISO file to load it into the USB disk.

Problems that occur after starting on the RHEL installation page. You are asking me to select the driver disk source, which I have no idea on which device the USB disk is mounted. I tried to randomly select all the options and it seems that device / dev / sda4 works for me. But then he asks me to choose the driver update image file, I have no idea what it is.

Can anyone help me with this?

SEO – Benefit of adding image by URL in wordpress?

In WordPress we can add images by three methods. 1.Upload, 2.Media Lib. and 3.Insert the image url. My question is, what is the benefit of SEO when you choose option 3 (Insert image URL)? because I use the first option (upload) in my blog Web page. so increase the speed of your page.

8 – twig check if image style or view mode exists

I have a site design that I need to implement.
In this design I have a grid and in the grid I can put any content (node ​​/ paragraph) that I choose.
the image of the content changes in size and proportion in relation to its location in the grid.
I created display modes for the nodes and use twig tweak to represent it in the correct display mode, for example:

{{ drupal_entity('node', content('#node').id , 'box_grid_1x2') }}

For paragraphs I add my image style directly in the paragraph template:

{{ content.field_image.0 | merge({'#image_style': 'box_grid_1x2'}) }}

because it's a bit more dynamic than this and my & # 39; box_grid_1x2 & # 39; It is actually a variable that the user can configure. I want to verify that my image styles of view modes exist before printing them and, if they don't, I want to print a backup copy. show image style.

how would you do it?
Thanks for your help.
